We have developed multiple-probe scanning probe microscopes (MP-SPMs) which is not only useful in revealing physical properties of individual nanostructures and nanomaterials but also in investigating nanoarchitectonically assembled nanosystems. In this seminar, as an example, I discuss about a study on complex networks of nanowires exhibiting interesting features such as a “small-world” property and 1/f behaviour. This study leads us to discuss about brain-type computation using nanoarchitectonic neuromorphic systems.
